Their opponents are world champions in the 50-over format, but England are world ranked number one by the ICC for ODIs.

"I don't know how many places are up for grabs but I would say a lot of them are," added Cook. "You want competition and people pushing hard to put out the people who are in the team now.

"It's going to be a hell of a challenge, a bit like the Test series in one way. We have to do something that no English side has done for a long time.

"Clearly we are the underdogs but if you look through our side we have got a lot of firepower and a lot of world-class players.

"For us to win the series, those world-class players and everyone else in our squad is going to have to play out of their skin."

Ashley Giles will be in charge of England for the first time since taking control of the limited-overs team from Andy Flower, and he is expected to include Jade Dernbach in the seam attack, alongside Steven Finn and Tim Bresnan.

Woakes and Meaker will compete for the final bowling place with Hampshire spinner Danny Briggs, who is yet to play on the trip.
